ADJUSTABLE CLAMP FOR PIPES.

Specification of Letters Patent.

Patented May 22, 1906.

invented a new and Improved Adjustable Clamp for Pipes, of which thefollowing is a full, clear, and exact description.

My invention relates to certain improvepatent on a fastening device, No.737,437, dated August 25, 1903.

The general purposes of my invention are similar to those accomplishedby the appa ratus described in said patent. It can be applied tohorizontal, vertical, or slanting walls and can be used with all kindsof pipes, for flag-poles and other devices which pass through walls. Itis essentially an adjustable escutcheon. for roof vent-pipes orroof-flanges, but for many other purposes, such as to cover holes madeby all kinds of pipes passing through Walls, and on steam-engine shaftsto keep oil from running down the shafts. While it may assist insupporting a roof or other structure, it is chiefly designed to form awater tight joint .and to provide means for keeping the joint tight ifthe roof settles or if the pipe expands or contracts.

Further objects of the invention will appear below.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of a device constructed in accordance withthe principle of the. present invention. Fig. 2 is a sectional view of asimilar device applied to a slanting roof. Fi 3 is a sectional view ofanother form of t e invention. Fig. 4 is a sectional view on the line 44 of Fig. 1. Fig. 5 is a perspective view of a detail. Fig. 6 is asectional view showing a modification. Fig. 7 is a longitudinalsectional view showing another way in which my invention may be used.Fig. 8 is an elevation of a modification, and Fi s. 9, 10, and 11 areperspective views of mo ifications.

To protect a pipe a, I provide a band 6, having a collar portion 1),adapted to fit the pipe 0., and provided, if desired, with a pack- Itcan be used not alone portion which is provided with corrugations bThese corrugations may eXtend around the band or may be appliedvertically, as desired, in order to take up expansion and contractionand other movements of the pipe or supporting means. This band is openat one point and is designed to overlap.

In order to provide for using the band for different purposes, I indexit, as shown by certain marks I). These marks are properly labeled, soas to show what kind of a pipe is intended to be employed. In the use ofthese indexes or marks the overlapping por tion of the pipe is broughtup to the mark which is indicated to conform to the kind of pipe withwhich the device is to be used, and the parts are then clamped ortightened in position. For the purpose of securing the parts together apair of brackets a are riveted to the band. One of these brackets isintended to receive a screw-threaded bolt (1, which may be straight orcurved. This bolt may be provided with a nut e, as shown in Figs. 1 and4, or the bolt may be headed on the outside of a flange c on thebracket. The other bracket is provided with an elongated slot 0 to allowfor the movement of the bolt caused by the tightening of the band andfor variations in the size of the pipe. Instead of a straight bolt acurved bolt may be employed.

When the band is used 011 a large pipe, I prefer to employ a lengtheningand strengthening piece f. This piece is provided with two flangesf,through which the bolts pass, and in this case a bolt is mounted betweeneach of these flanges and the flange of one of the portions 0. Thisstrengthening-piece bears against the pipe or directly against the withnuts or heads, or they can be screwed in the threads in the flanges cand f, as shown in Fig. 6. The packing for the device may be of anydesired kind or character and is indicated at gin Figs. 2, 3, and 7. Itis made '11 the form of a washer of soft graphite or of a cement whichremains elastic and allows the expansion and contraction of the parts.In Fig. 7 also I have shown a modified construc tion in which the bandextends over the top of a funnel h, which is soldered to the roof.Between the band and funnel is formed a space which is filled by awedgeshaped packing k, also formed of a washer of soft graphite or thelike, as stated above.

The modification shown in Fig. 8 represents a band 6 formed with theother features specified above, and instead of being convex, as theother forms are, is made in the form of a cone.

In Fig. 9 I have shown another form of fastening device, in which ascrew d is provided, with a flattened portion d riveted to the neck ofthe band. This screw is provided with a nut d in the ordinary manner,which can secure the screw to a bracket on the other side or to thelengthening-piece f. The lengthening-piece shown in Fig. 9 is providedwith an open slot f 2 instead of a perforation.

In Figs. 10 and 11 I have illustrated two other forms of simplefastening devices which I can employ. In the former figure I slit theband or its neck on parallel lines and force out a projection b Thisleaves an opening 6 through which a bolt or screw from the other end ofthe band can be passed. In Fig. 11 a tongue I) is formed on the end ofthe band, and this is provided with a perforation b for the reception ofa fastening device. All these features can be used in combination withthe devices shown in the other figures.

In all of the forms of my invention the vertical seam, where the ends ofthe bandbcome together, is soldered, and the brackets are placed farenough apart to permit a soldering-tool to be inserted for this purpose.

This invention is designed to replace the old method which is now inusenamely, the cutting of the pipes having a hub, so that the hub willcome even with the roof, and setting sheet-lead into the hub to secureit to another joint of pipe. tates waste of pipe, and the sheet-leaddoes not form a permanent or perfect oint. By the construction specifiedI form the device with a minimum amount of metal and allow for expansionand contraction in a most efficient manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A clamping device for pipes, comprising anadjustable band, a pair of brackets thereon, each having a perforatedflange, one of the brackets being elongated, a lengthening andstrengthening piece located between the brackets and bearing against theband, said lengthening-piece having perforations, and a bolt passingthrough the perforations of the strengthening-piece and a perforation ofone of the said brackets.

2. In a clamping device for pipes, comprising a band passing around thepipe, a pair of brackets on the band, a strengthening-piece between thesaid brackets having perforated flanges at its ends and adapted to bearagainst the band, said strengthening piece being curved to conformsubstantially to the shape of the pipe, and means for adjustablysecuring the flanges of said strengthening-piece to the brackets.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
